[0047] Further optimize the plan, such as Figure 1 and 2 As shown, filter accessory 2 can be fixedly connected to filter body 3, or filter accessory 2 can be in contact with filter body 3, or, as... Figure 6 As shown, the filter accessory 2 is fastened to the filter body 3, or other connection methods are used, depending on actual needs. No specific requirements are made here. The filter accessory 2 is located on the outside of the filter body 3 to further filter the filtered water and further purify the water filtered by the filter body 3.

[0048] The aforementioned filter accessory 2 is equipped with a filter element 5, which filters the water again after it has been filtered by the filter body 3. The filter accessory 2 also includes an installation frame, in which the filter element 5 is housed. The installation frame serves as a skeleton to facilitate the installation of the filter element 5.

[0049] In some feasible embodiments, the mounting frame includes a side plate and an annular circumferential side plate disposed on one side of the side plate. The side plate and the annular circumferential side plate form a receiving space, in which the filter element 5 is disposed. In this structure, the filter accessory 2 contacts and engages with the filter body 3.

[0050] In other feasible embodiments, such as Figure 6 As shown, the mounting frame is a plate-like structure, and its shape is adapted to the internal shape of the housing 1. The mounting frame is provided with multiple filter holes 300. The mounting frame is fastened to the filter body 3. The filter element 5 is located between the filter frame and the filter body 3. Through the fastening connection, the filter element 5 is fixed between the filter frame and the filter body 3. In this structure, both the filter body 3 and the filter accessory 2 are fastened to the housing 1.

[0051] In this embodiment, preferably, the filter element 5 is a sponge filter core. The sponge filter core can adsorb while filtering, so even very small pieces of garbage can be filtered out.

[0052] In this embodiment, preferably, the number of pores in the sponge filter core is 30-60 PPI, where PPI refers to the number of pores per square inch, and the thickness of the sponge filter core is greater than 1 mm, preferably 1-20 mm.

[0053] When the filter accessory 2 is slidably connected to the housing 1, a set of oppositely arranged side walls of the housing 1 are provided with guide blocks 10, and a set of oppositely arranged side walls of the filter accessory 2 are provided with guide grooves 20. The guide blocks 10 and guide grooves 20 are inserted into each other so that the filter accessory 2 can slide along the guide blocks 10. When installing the filter accessory 2, the guide blocks 10 are inserted into the guide grooves 20 to apply force to the filter accessory 2, which can press the filter accessory 2 into the housing 1, so as to achieve accurate positioning and quick installation of the filter accessory 2. At the same time, the guide blocks 10 limit the movement of the filter accessory 2 along the length direction of the housing 1 to prevent the filter accessory 2 from deviating. The guide groove 20 is a groove structure, which is set on the two sides of the mounting frame of the filter accessory 2 facing the inner wall of the housing 1. It is formed by indentation from the side and the guide groove 20 is set along the length of the mounting frame. The guide block 10 is a protruding structure, which is installed on the inner wall of the housing 1 facing the guide groove 20 and protrudes from the inner wall of the housing 1. The protrusion on the inner wall of the housing 1 can block the gap between the filter accessory 2 and the inner wall of the housing 1, enhance the sealing between the filter accessory 2 and the housing 1, and prevent solid impurities in the sewage from leaking out from the gap between the filter accessory 2 and the inner wall of the housing 1.

At the same time, the sealing element 4 is elastic. When the filter accessory 2 is installed, the sealing element 4 is compressed and can undergo elastic deformation to seal the contact point between the filter accessory 2 and the bottom plate of the housing 1. When the filter accessory 2 is removed, the sealing element 4 applies elastic force to the filter accessory 2 under the action of elastic deformation, and the filter accessory 2 is separated from the bottom plate of the housing 1, which facilitates the disassembly of the filter accessory 2.

[0055] The filter accessory 2 can be plugged into the bottom plate of the housing 1. A groove is provided on the bottom plate of the housing 1, and the filter accessory 2 is plugged into the groove, with the seal 4 installed in the groove; or, the seal 4 is installed on the end of the filter accessory 2 facing the bottom plate of the housing 1. After the filter accessory 2 is installed, the seal 4 contacts the bottom plate, and the seal 4 seals the contact point between the filter accessory 2 and the bottom plate of the housing 1. Other installation methods may also be used, depending on actual needs. No specific requirements are specified here.

[0056] In this embodiment, preferably, the sealing element 4 is a sealing strip.

[0057] When the underwater cleaning device is in operation, taking the filter body 3 as an example of the filter frame structure, the inlet assembly is installed at the inlet of the filter body 3, and the inlet assembly is located inside the filter body 3 (when the filter body 3 is a plate structure, the inlet assembly is installed at the inlet of the housing 1). The filter frame 30 is fastened to the top cover 31, and then the filter body 3 with the inlet assembly is installed inside the underwater cleaning device. The inlet on the bottom plate is aligned with the inlet of the inlet assembly so that sewage can enter the filter body 3. The guide groove 20 of the filter accessory 2 corresponds to the guide block 10 of the housing 1. The guide block 10 is inserted into the guide groove 20, and a force is applied to the filter accessory 2. The filter accessory 2 slides along the guide block 10 and is installed inside the housing 1.

[0058] The underwater cleaning device is placed underwater to perform cleaning operations. The cleaning roller brushes the bottom and walls of the pool. The sewage is pushed open by the impeller's suction and enters the filter body 3. After being filtered by the first filter element of the filter body 3, the filtered water is filtered again by the filter element 5 of the filter accessory 2. The filtered water is discharged from the outlet of the underwater cleaning device, and solid dirt is trapped in the filter body 3.

[0059] After the underwater cleaning device stops working, the valve device is returned to its original position, the inlet is sealed, and the filter device is removed for cleaning so that it can be used again.

[0060] Due to the adoption of the above technical solution, the filtration device has a filter body, which is equipped with a filter frame and a top cover that are snapped together. Both the filter frame and the top cover are equipped with filter screens to filter sewage. One end of the filter frame is connected to a bottom side plate, and the bottom side plate is equipped with a water inlet. Sewage can enter the filter frame through the water inlet, and the filter frame can filter the sewage. The top cover is located at the other end of the filter frame to prevent solid waste from flowing out. Solid waste is trapped in the filter body. The filter body has a simple structure, which can make full use of the installation space inside the underwater cleaning device and is easy to install and disassemble. The filtration device is equipped with a filter accessory for secondary filtration of sewage. The filter accessory is equipped with a sponge filter element, which absorbs while filtering sewage, further improving the cleanliness of the filtered water. A sealing element is provided at the contact point between the filter accessory and the bottom plate of the housing to seal the contact point between the filter accessory and the bottom plate of the housing, preventing sewage from flowing out from the contact point between the filter accessory and the bottom plate of the housing without being filtered by the filter accessory. The sealing element has an elastic element that undergoes elastic deformation during the installation of the filter accessory to seal the installation position of the filter accessory.
